Habaneros are a little more difficult to start and generally require at least 7 - 14 days to germinate. Some will take upwards of 21 - 30+ days. Soil temperature is the key, to hot or too cold little to no germination. Your soil should remain moist, not too wet, but shouldn't dry out. The temperature of the soil should be between 75 - 85 degrees, with 85 / 86 ideal. Don't take it above 90 at 95+ germination drops off. Planting depth shouldn't be more then 1/4.
The potential for germination will continue for almost four months, but after this time the germination rate is several fold less and germination time is significantly longer. Fresh seeds should germinate in 2.5 months, but old seeds can take as long as 6 months. Coffee in pergamino is even better. If this is available plant the coffee face down in the pergamino. It is advisable to pre-germinate the seeds. First soak the coffee seeds in water for 24 hours.
